一种用于移动传感器网络的定位算法

无线传感器网络作为一种全新的信息获取和处理技术,可以在广泛的应用领域内实现复杂的大规模监测和追踪任务。在传感器网络中,定位问题已经是很多无线传感器网络应用的关键,以前的大多数定位算法只适用于静态网络。设计了一种适用于锚节点和普通节点都自由移动的移动传感器网络的定位算法,该算法结合Monte Carlo和RSSI方法,通过约束选取样点的样本空间,仿真结果显示同比提高了算法精度。

An Accurate Localization Algorithm for Mobile Sensor Networks

As a new technology of data-gathering and data processing,WSN is widely used in many application area,such as target monitoring and tracking.Localization is crucial to many applications in wireless sensor networks,but most of Algorithm is just used in static WSN.In this paper,we designed an accurate localization algorithm for mobile sensor networks consisted of floating anchors and floating ordinary nodes,this algorithm combine the method of Monte Carlo and RSSI,by constraining the area where the samples are drawn,the simulation result show that this algorithm have a improved accuracy.
